EBENEZER CLARK, OF RUSHVILLE, ILLINOIS.

SAW.

Specification of Letters Patent No. 6,258, dated April 3, 1849.

To all 'whom t may concern.'

Be it known that I, EBENEZER CLARK, of Rushville, in the county ofSchuyler and State of Illinois, have invented a new Saw; and I do herebydeclare that the following is a full and eXact description of theconstruction and operation vof the same, reference being had to theannexed drawings, making part of this specification, in which- Figure l,is a vertical sectional view. A, is the blade. B, is flatmovable teethwhich are inserted on both sides of the blade, in dovetail grooves, andwhich are made long so that they may be let down as fast as thev wear,very sharp and thin at the point so that they may sink as much aspossible. C, the cleaving teeth, or which might be called splitters in across cut saw they hang on a rivet or screw quite loose (those oi themiddle being too tight) they are placed be tween every pair of the flatteeth, B, and the points of every other one are placed in oppositedirections so that when the saw is pulled to the right the points ofthose which are turned to the left will raise and admit those turned tothe right to gouge or clear.

Fig. 2, is a perspective view of A, in Fig. l,V I), are the dovetailedgrooves in which clears at the same time. Secondly. It will cut a greatdeal more in the same space of time. Thirdly. The teeth can be made ofthe best kind ot' steel and the quantitv required will be comparativelysmall. Fourthly. It will zeep sharp longer, the friction not beingacross the edge of the teeth, as in the old. Fifth. It any of the teethshould break they can be replaced at little expense. Sixth. The bladecan be made of solid iron and will last a mans life time.

That I claim as my invention and desire to secure by Letters Patent is-The movable and loose teeth, (B, and C,) in any kind of saw regardlessof shape or form, or manner of insertion for I am aware that they can bemade, in other shapes and placed in blades made different that wouldanswer as well.

EBENEZER CLARK.
